The number of group participants from each member country is limited by two people: one expert with an exposure to the field and one young professional. Experts are expected to be members of CIGRE, but it is not a prerequisite. Terms of reference of all active working groups and scope of work and activities of all study committees can be found in the relevant section of the CIGRE website. The rules which govern the activities of the study committees can be found in the Guidelines for SC Activities section of the website.

The candidates to act as experts are proposed by CIGRE national committees. Acceptance of the candidates is the responsibility of the CIGRE study committee chairmen. Once approved by the SC chairman, candidates’ proposal is submitted to the CIGRE technical committee for approval. [cigre.org]
